Numerical symbols are characters used to represent numbers in mathematics and everyday life. The most common numerical symbols are the digits from 0 to 9, which combine to form larger numbers. For example, the number 25 is made up of the digits 2 and 5. These symbols help us count, measure, and perform calculations. In addition to basic digits, there are other numerical symbols like + for addition, − for subtraction, and × for multiplication. These symbols allow us to express mathematical operations clearly and efficiently. Understanding numerical symbols is essential for solving problems in math and science.
